Description
Technical Field
The utility model relates to a supporting cone crusher lower body that has wear-resisting welt. The cone crusher is mainly applied to mine concentrating mills and ore crushing places.
Background
As prior art, the wear-resisting welt is generally all installed to cone crusher lower body inner wall, and in order to prevent to drop, wear-resisting welt generally welds on cone crusher lower body inner wall. In the production process, due to ore abrasion, the lining plate needs to be replaced regularly, especially the abrasion of the upper part of the abrasion-resistant lining plate and a welding part is serious, and if the abrasion is not timely caused, the lower machine body of the cone crusher is abraded and even damaged. Because the inner space of the lower machine body of the cone crusher is narrow, when the wear-resistant lining plate is replaced, a welding task needs to be completed in the inner space of the lower machine body manually, the labor intensity is high, the operation environment is poor, the operation time is long, and the time for replacing the wear-resistant lining plate once is 3-4 hours generally. On the other hand, the existing wear-resistant lining plate is generally of a single-layer structure, has poor wear resistance and unsatisfactory service life.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to provide a lower machine body of a cone crusher with an easily replaceable wear-resistant lining plate, firstly, the replacement operation of a wear-resistant component is simplified by improving the installation mode of the wear-resistant component; secondly, the service life of the wear-resistant component is further prolonged.
The technical scheme of the utility model as follows:
organism under cone crusher with wear-resisting welt of easily changing, including cone crusher's lower organism section of thick bamboo wall with be used for being fixed in two at least wear-resisting welt subassemblies on the lower organism section of thick bamboo wall inner wall, its characterized in that: a plurality of bolt holes in the form of through holes are formed in the cylinder wall of the lower machine body; the wear-resistant lining plate components with the adjacent end parts butted form a cylindrical lining plate component which is attached to the inner side of the cylinder wall of the lower machine body of the cone crusher; the wear-resistant lining plate assembly comprises an arc-shaped foundation plate and an arc-shaped wear-resistant plate attached to the inner side surface of the arc-shaped foundation plate; bolts which are arranged along the radial direction of the lower machine body of the cone crusher are fixed on the outer side of the arc-shaped foundation plate; the bolts penetrate through the corresponding bolt holes and are fastened by installing nuts on the outer side of the lower machine body cylinder wall, so that the wear-resistant lining plate component is tightly attached to the inner wall of the lower machine body cylinder wall.
Preferably, the arc-shaped base plate is a steel lining plate, and the arc-shaped wear-resisting plate is a surfacing layer.
Preferably, the bolt hole is located in the area between one fourth of the distance from the bottom end of the lower machine body cylinder wall and one fourth of the distance from the top end of the lower machine body cylinder wall.
Further preferably, the bolt hole center position is located at an axially intermediate position of the lower machine body cylinder wall.
Preferably, the number of wear liner assemblies is four.
The utility model has the advantages of:
first, through bolted connection wear assembly, the bolt is fixed mutually with lower organism after wearing out from cone crusher's lower organism section of thick bamboo wall, and the operator need not carry out operations such as welding in organism inside down during the installation wear assembly, and when wear-resisting welt was changed, only need pull down the nut on the screw rod from cone crusher lower organism outside, again from cone crusher lower organism inside will wear and tear the welt subassembly pull down can. The structure is simplified, the operation environment and the operation convenience are improved, the working efficiency is greatly improved, and the replacement time of the wear-resistant component is 1/4-1/8 of the time of the original replacement mode (namely, the wear-resistant lining plate is welded on the lower machine body).
Second, the utility model discloses a wear-resisting welt subassembly has steel sheet basal layer and build-up welding layer, and the material finishes the back with the wearing and tearing of build-up welding layer, and the steel sheet basal layer continues to use as the wearing layer, and whole life is about the twice of original cone crusher welt.
Third, the utility model discloses a wear-resisting welt subassembly price is lower for original cone crusher welt price to but the manufacturing by oneself.

Fig. 1 is a schematic structural diagram of a lower machine body of a cone crusher according to the present invention.
Fig. 2 is a schematic structural view of the wear-resistant lining plate assembly of the present invention.
In the figure, 1: lower body cylinder wall, 2: bolt hole, 3: arc foundatin plate, 4: arc antifriction plate, 5: and (4) bolts.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, the utility model discloses an implementation includes cone crusher's lower organism section of thick bamboo wall 1, set up the bolt hole 2 of a plurality of through-hole form on the lower organism section of thick bamboo wall 1.
The utility model discloses an implementation still includes at least two wear-resisting welt subassemblies as shown in fig. 2, and the quantity of wear-resisting welt subassembly is generally two to eight, preferably four.
